Fundamentals of ANNs
Artificial neural networks (ANNs) are computational models inspired by the structure and functionality of the neural networks of the human brain.ANNs consist of layers of interconnected nodes or neurons, typically organized into an input layer, hidden layers, and an output layer.Neurons in each layer are connected to neurons in adjacent layers through weighted connections.These weights are adjusted during the training phase, allowing the network to learn and adapt to patterns in data [3].The architecture of ANNs mirrors the neural structure of the human brain, facilitating the learning and decision-making processes.While simpler than the human brain, ANNs excel in pattern recognition, making them adept at analyzing complex datasets, especially relevant in the context of cardiac diagnostics.
ANNs function through a process known as forward propagation, where input data is passed through the network and predictions are generated at the output layer.During training, a backpropagation algorithm adjusts the weights based on the prediction error, enhancing the network's accuracy over time.In the realm of cardiac diagnostics, ANNs process various patient data such as medical history, test results, and lifestyle factors.Studies have explored their effectiveness in diagnosing coronary artery disease, myocardial infarction, and other cardiac disorders [1,2,4,5].This comprehensive approach enables them to identify subtle patterns indicative of cardiac pathology.Their ability to adapt to evolving datasets enhances diagnostic precision.Compared to traditional diagnostic methods in cardiology, ANNs offer a more dynamic and adaptable approach.Traditional methods may rely on predetermined algorithms and predefined criteria while ANNs learn from data patterns, potentially uncovering nuanced insights that conventional methods might overlook.This adaptability positions ANNs as valuable tools in the evolving landscape of cardiac diagnostics.
